I take it that you're building for 64-bit?  The error message is related
to casting a 64-bit pointer to a 32-bit int for log output.  I'll amend
the code to use a 64-bit compatible type.

Actually, I believe that the compiler is wrong to emit an error here.  A
warning is acceptable, but the code includes an explicit cast from
pointer to int which the compiler should honour.  Are you using
additional compiler warning options?

OK, I've fixed the patch.  Try re-downloading and building.

Thanks for your feedback.
